Peppol BIS Message Level Response, often abbreviated as MLR, is a response message used to inform the sender about the status of a received business document at message level.
The message can be used when the receiver wants to confirm that a document, such as an order or invoice, has been received and validated. MLR can also be used to indicate that the document has been rejected due to technical errors, syntax errors, or non-compliance with applicable validation rules.
A Message Level Response can, for example, indicate that:
- the document has been received and identified as a business document
- the document has been validated without fatal errors and can be processed further
- the document has been rejected due to validation errors
- the sender needs to correct and resend the document
MLR should be distinguished from transport receipts and business-level response messages. Transport receipts relate to the actual transmission of the message through the network. Business-level response messages relate to decisions made after a document has been accepted for processing, for example if an order is rejected due to stock availability or an invoice is disputed for business reasons.
Peppol BIS Message Level Response is based on UBL ApplicationResponse 2.1 and is used together with Peppol validation rules to support automated handling of status information and errors in document exchange.
